A herbal composition comprising supercritical fluid extracts/oils of Jyotishmati,  Bacopa monnieri,  Ginger Oil, Flax Seed oil, Rosemary Ext and Vitamin E is effective in the treatment of symptoms associated with Attention Deficit disorder (ADD) and Attention deficit/hyperactivity disorder (ADHD).

TECHNICAL FIELD

The present invention relates to synergistic herbal compositions useful in the treatment of Attention Deficit disorder (ADD) and Attention deficit hyperactivity disorder (ADHD). More particularly the invention relates to a herbal composition capable of reducing the ADD/ADHD symptoms, which also helps to improve memory and cognitive skills in adolescents and adults. The invention further relates to method for treating the same.

BACKGROUND AND PRIOR ART

Attention Deficit Disorder (ADD) and Attention Deficit Hyperactivity Disorder (ADHD) (severally and collectively hereinafter referred to as “ADHD”) are developmental disorders, largely neurological disorders affecting 5% of the world population. The disorder typically presents itself during childhood, and is characterized by a persistent pattern of inattention and/or hyperactivity, as well as forgetfulness, poor impulse control or impulsivity, and distractibility.

Inattentive behaviour is often characterized by difficulty focusing on one task, failure to pay attention to details, and making careless mistakes in a variety of tasks. Individuals exhibiting inattentive behavior may appear as if their minds are elsewhere or they are not listening or did not hear what has just been said.

Hyperactive people always seem to be in motion and may suffer from feelings of restlessness and difficulty engaging in sedentary activities. Common signs include excessive unproductive movement, excessive talking, and an inability to sit still. Hyperactive children often roam around the room, and feel compelled to touch everything.

Impatience and a failure to think before acting often characterize impulsivity. Impulsive young children may frequently interrupt others, fail to listen to directions, and have difficulty waiting for their turn.

These problems are reflected in impairment of a person's will or capacity to control his or her own behavior relative to the passage of time and to keep future goals and consequences in mind. ADHD is most commonly diagnosed in children and, over the past decade, has been increasingly diagnosed in adults. About 60% of children diagnosed with ADHD retain the disorder as adults.

Studies indicate that the disorder is highly heritable and that genetics contribute about three quarters of the total ADHD population. While the majority of ADHD is believed to be genetic in nature, ⅕ of all ADHD cases are thought to be acquired after conception due to brain injury caused by either toxins or physical trauma parentally or postnatally. Scientists have not yet identified a single underlying cause behind these behavior characteristics. While some have been linked to decreased brain activity, the biological reason for the decreased brain activity is still unknown. Treatment for ADD and ADHD is therefore limited to treating the symptoms of the disorders.

Methods of treatment usually involve some combination of medications, behaviour modifications, life style changes, and counseling.

The most common treatment for ADD and ADHD is the use of mild central nervous system stimulant drugs, such as Ritalin, Cylert, and Dexedrine. However, there are several drawbacks in using these drugs such as frequent short-term side effects include insomnia, loss of appetite, headaches, stomachaches, hyperactivity, drowsiness, blood pressure and pulse changes, and cardiac arrhythmia. In addition to this, the possible consequences of long-term exposure to these drugs in children are not thoroughly investigated. The use of Ritalin in children under six years of age is particularly undesirable since safety and efficacy in this age group has not been established.

As an alternative to the aforementioned conventional treatments, U.S. Pat. No. 5,719,178 discloses a method for treating ADHD comprising taking a quantity of proanthocyanidin sufficient to relieve symptoms of ADHD every 3.5 to 4.0 hours. A heterocyclic antidepressant, preferably desipramine may be taken optionally with the proanthocyanidin in quantities sufficient to attenuate ADHD-related symptoms of lack of cognitive focus. However, a major drawback of this method is that repeated doses are required to alleviate symptoms throughout the day, which is inconvenient as well as difficult especially for school going children.

U.S. Pat. No. 6,093,404 describes a therapeutic composition for treatment of ADD or ADHD comprising in percentage by weight: 3-9% proanthocyanidin, 30-40% yucca root, 15-25% hawthorn berry, 10-20% bilberry, 5-15% silymarin, and 10-15% gingko biloba.

U.S. Pat. No. 6,759,053 provides compositions and methods for using the S(+) enantiomer of desmethylselegiline (N-methyl-N-(prop-2-ynyl)-2-am-inophenylpropane), for the treatment of selegiline-responsive diseases and conditions. Diseases and conditions responsive to selegiline include those produced by neuronal degeneration or neuronal trauma and those due to immune system dysfunction. Effective dosages are a daily dose of at least about 0.015 mg/kg of body weight.

The use of 3-[1-[2-(1-acetyl-2,3-dihydro-1H-indol-3-yl)ethyl]-1,2, 3,6-tetr-ahydropyridin-4-yl]-6-chloro-1H-indole, any of its enantiomers and pharmaceutically acceptable salts thereof for the preparation of a pharmaceutical composition for the treatment of Attention Deficit Hyperactivity disorder is disclosed in US20040152737.

The pharmaceutical compositions are comprised of a therapeutically effective combination of a nicotine receptor partial agonist and an anti-ADHD agent and a pharmaceutically acceptable carrier and the method of using these compounds is disclosed in US20040220184

WO2003068251 describes herbal formulation comprising Bacopa monneri; Centella asiatica; Glcyrrhiza glabra; Withania somnifera and Celastrus paniculatus and process for preparing the same for treating Attention Deficiency Disorder in Humans. The herbs are subjected to solvent extraction using hazardous solvents such as hexane, chloroform, methanol and acetone. The herbs are extracted especially Brahmi and Jyotishmati using Hydrocarbon solvents such as Hexane, Chloroform which are considered hazardous to human health. The extraction of the herbs at higher temperature destroys or modifies molecular and chemical structure of temperature sensitive phytochemicals which may contribute to the therapeutic value of the herbs.

In a conventional solvent extraction process, the separation temperature is always greater than the extraction temperature. This means that when the solvent is recovered, the obtained extract is subjected to higher temperature, which is likely to destroy many temperature sensitive phyto nutrients and phyto chemicals in the extract.

A combination of hyperforin, 5-hydroxy triptophan, rhodiola rosea, along with Vitamins B, Vitamin C, Vitamin D3, and minerals like selenium and Zinc are sold under the brand name of Amoryn for treating ADHD disorders. The daily dose comprises 1 to 4 capsules per day.

There is a need in the art to provide herbal formulation for oral administration comprising safe and effective extracts of two or more herbs, effective for the treatment of ADHD, and is devoid of any side effects.

SUMMARY OF THE INVENTION

Accordingly, in one aspect, the invention discloses herbal composition comprising two or more effective extracts of the herbs selected from Acorus calamus, Azadirchta indica, Bacopa monnieri, Boswellia serrata, Eclipta alba, Embelia ribes, Fumaria indica, Linum usitatissimum, Celastrus paniculatus, Mucuna pruriens, Nardostachys jatamansi, Nigella sativa, Ocimum sanctum, Phyllanthus niruri, Rosmarinus officinalis, Ricinus communis, Valeriana officianalis and Zingiber officinale useful in the treatment of ADHD.

In another aspect, the invention discloses method of extraction of the herbs used in the invention. The herbs are extracted using a unique method of extraction, so as to ensure that the extractives are safe and effective and contains no harmful extraction solvents.

The supercritical CO2 extraction which is used in the present invention with or without entrained ethanol does not leave any hazardous solvent residues. The extraction temperature is maintained between 35° C. to 45° C., which ensures the retention of all temperature sensitive ingredients.

The method adopted by the present inventors for extraction (Supercritical CO2 extraction with or without entrained ethanol) always has a much lower separation temperature than the extraction temperature. Thus integrity of phytonutrients and phytochemicals is maintained apart from retaining the temperature sensitive ingredients (Typical separation temperature for conventional extraction is 45° to 80° C. while the separation temperature will be around 20° C. to 25° C. in the present process) So in conventional extraction separation temperature for recovering the solvent from extracted material is always higher than the extraction temperature.

In a further aspect, the invention describes a method of treating Attention Deficit Disorder (ADD) and Attention Deficit/Hyperactivity Disorder (ADHD) using the compositions of the present invention. The invention also relates to using the formulation/composition for improving cognitive skills and memory.

(Synopsis of Clinical Evaluation of the Composition of Invention):

A Study of safety and Efficacy of Capsule C on ADD/ADHD (Attention Deficit Hyperactivity Disorder) in Adolescents was Carried Out with Following Objectives:

Primary End Point:

1. Reduction in ADHD Score.

2. Clinically meaningful reduction in ADHD symptoms.

Secondary Endpoint:

3. Improvement in scholastic performance of student.

4. Improvement in Intelligent Quotient (IQ) of student:

5. Overall improvement in mental status

Safety Evaluation for the Composition for Long Term Intervention:

School children were predominantly screened on the basis of questionnaires and the Diagnostic and Statistical Manual of Mental Disorders (4th ed.) criteria (DSM-IV) for hyperactivity after taking written informed consent from school principal of one of the leading High School, in Pune as well as their parents. Those children who were found to be hyperactive as per parents and teachers questionnaires, were informed about the study and informed consent were taken for enrollment of their child in the study. Further these children were valuated for inclusion exclusion criteria and also undergone lab and ECG investigations. Those who found to be eligible were enrolled in the study. Subjects were randomized to one of the two treatment groups.

Per Protocol Analysis:

First Phase Study:

The subjects were enrolled in a double blind and randomized fashion. The subjects were randomized to one of the two treatment groups (Group A and B). Those randomized to Group A received placebo 2 caps 100 mg twice a day for 3 months (49 subjects). Subjects randomized to Group B received capsule C 2 caps 100 mg twice a day for 3 months (48 subjects). All the subjects underwent medical and physical examination and evaluation for ADHD Dupal's score every 15 days. Duration of 1st Phase was 3 months. Placebo capsules contain 100 mg sesame oil. Capsule C contains 100 mg of formulation as described in the current invention. The Comparison of efficacy between placebo and Capsule C is discussed in table V.

TABLE V Comparison of efficacy between placebo and Capsule C Dupaul's ADHD score Significance Group A Group B Level (Placebo) (Capsule C) (Group A Vs Time point (n = 39) (n = 32) Group B) Significance Baseline 19.84 ± 5.28 18.88 ± 3.81 0.39 NS 90 days  9.86 ± 5.45  6.96 ± 3.54 0.01 HS ** Unpaired ‘t’ test is applied, p value is significant if p < 0.05. NS—Not Significant HS—Highly significant

From the above, in-group A, mean Dupaul's ADHD scale scores were 19.84 and 9.86 at baseline and at 3 months respectively. Corresponding findings in-group B were 18.88 and 6.96 respectively. ADHD score reduced from baseline to 90 days in both the groups. There is no statistically significant difference between the ADHD score of group A and Group B at baseline but the difference is significant at the end of 90 days. This clearly shows that the capsule C is highly effective in reducing the symptoms of ADHD.

Evaluation as Per DSM IV Criteria:

As per DSM IV criteria, in combined type of ADHD, 54.05% subjects showed improvement at 3 months in Group A (placebo), while 73.52% subjects showed improvement in Group B (capsule C). In predominantly Inattentive type, 63.63% subjects showed improvement at 3 months in Group A (placebo), while 85.71% subjects showed improvement in Group B (capsule C) and in predominantly Hyperactive-Impulsive type, 87.5% subjects showed improvement at 3 months in Group A (placebo), while 90.90% subjects shows improvement in Group B (capsule C). This clearly shows efficacy of the composition for improving the symptoms of ADD/ADHD. The details are given in table VI.

TABLE VI Efficacy measurement at baseline and at 90 day (PPP analysis).

Second Phase Study:

Evaluation of the composition for long term safety and efficacy (91st day to 360th day):

In second phase, the subjects were enrolled in an open label and non-randomized fashion. Responders, who exhibited at least 30% reduction in their symptoms, were calculated on the basis of Dupaul's scale and DSM IV in both the groups. The responders from the study group were continued for further study and higher dose of the study drug was given to them. The non-responders, who received Capsule Cin first phase, were excluded from the study.

In this phase of the study, the subjects were enrolled in two groups. In Group A, all the subjects who responded to Capsule C and 50% of subjects who responded to placebo in first phase were enrolled. In Group B, remaining 50% of subjects who received placebo in first phase were enrolled.

Group A subjects received 3 capsule of Capsules C (higher dose) twice a day while Group B subjects received 2 capsule of Capsules C (lower dose) twice a day. The dose pattern was continued till the end of the study. Subjects were followed through 90 to 360 days. All the subjects underwent medical and physical examination every 15 days. DSM IV criteria and assessment of ADHD on Dupaul's ADHD scale were also performed every 15 days. Mental examination was carried out monthly and intelligent quotient at baseline and day 90, 180, 270 and 360.

Clinical laboratory tests were performed at baseline and at day 90, 180, 270 and 360. Parents were inquired for development of adverse and serious adverse event at each visit.

Efficacy in Second Phase:

The objective of this phase was to establish the long term efficacy and safety of the high as well as low dose of capsule C.

Second Phase (High Dose Vs Low Dose):

Mean Dupaul's ADHD scale scores of subjects receiving higher dose are 6.3, 7.8, 6.4 and 8.0 at 90 days, 180 days, 270 days and 360 days respectively. Corresponding findings in subjects receiving lower dose were 10.2, 9.7, 7.9 and 7.9 at 90 days, 180 days, 270 days and 360 days respectively. Significant difference was seen between the ADHD score of group A and Group B at 90 days. No significance difference was seen at 180 days, 270 days and 360 days. The details are given in table VII.

TABLE VII Comparison of efficacy between two doses of Capsule C. Dupaul's ADHD score Significance Time point Higher dose Lower dose Level Significance  90 days 6.3 ± 3.3 10.2 ± 6.3  0.01 HS 180 days 7.8 ± 5.3 9.7 ± 7.4 0.28 NS 270 days 6.4 ± 4.9 7.9 ± 6.5 0.37 NS 360 days 8.0 ± 6.8 7.9 ± 7.6 0.96 NS ** Unpaired ‘t’ test is applied, p value is significant if p < 0.05.

Mental Examination (IQ Scores of Student):

The mean mental examination score improved from baseline to 360 days in both the groups. Following table shows the statistical analysis of IQ scores for both the groups.

IQ Analysis:

0 day IQ 360^(th) IQ n 85 47 Mean 87.13 90.11 SD 5.59 9.45 Paired t test Day 0 Vs 360 0.024*

The 1 year completers shows statistically significant difference in the IQ scores at the end of the phase III (360^(th) day) than that of baseline (0^(th) day) by parametric as well as non-parametric tests.

Moreover, the mean mental examination score improved from 0 days to 360 days in both the groups but the difference between mean changes in score is not statistically significant. This indicates that both the higher dose as well as lower dose is improving the IQ scores on Weschler scale

Scholastic performance was considered as one of the criteria in assessing the results of the study treatments. Moreover, sitting at a place and studying is generally difficult for an ADD/ADHD child. Hence duration for which a student sits and study was noted. Irrespective of the results of the exams, an increase in the study time would point towards the efficacy of the drug. An increase in attentiveness and decrease in the hyperactivity leads to increased study time.

All the students were evaluated for progress in various subjects (Marathi, Hindi, English, Mathematics, science, social science) in mid semester and final examination conducted by the schools to see the improvement. There was a marked improvement in the study time as well as scholastic performance when the scores of first and second semester were examined statistically.

Conclusion:

From the above it is evident that ‘Capsule C’ significantly improves the symptoms of ADHD as compared to placebo in children and adolescents of 8-16 years of age. The treatment is also effective in improving the core symptoms of ADHD, namely inattention, hyperactivity, and impulsivity, both at school and at home. Lower dose of the capsule C is as good as high dose and effective and safe when used for long period of time.

Example: 8

Effect of Capsule C on the FA Profile Post Treatment:

In this trial, 23 patients were administered higher dose of capsule c (one 300 mg capsule two times a day) to study the effect of capsule C on Fatty acid profile in the patients blood. Blood samples were collected from all the subjects before administering the capsule on 0th day and then a blood sample was obtained on 90th day. Samples were analyzed at Dept. of Biotechnology, Sinhgad College of Engineering, Pune.

Method of Analysis:

Fatty Acid Analysis:

RBCs samples were analyzed. Isolation of fatty acids and methyl esterification of fatty acids was done by the following method:

-   -   1. Extracting lipids using 2:1 chloroform/methanol.     -   2. Methyl esterification with Methanolic HCl (0.6N HCl/methanol)         at 80° C. for 2 hrs.     -   3. Separating the esters and quantifying on GC by capillary         column (BPX 70)

Thiobarbituric Acid Reactive Assay (TBAR):

-   -   1. Treating Plasma with 10% TCA (Trichloro aceticacid) and then         with 0.6% TBA (Thiobarbituaric Acid).     -   2. Heat treating it for 10mins at 90° C.     -   3. Centrifugating at 3000×g for 10mins and then reading optical         density at 530nm against water blank.

Statistical Analysis:

The statistical analysis of the data was done using software (Software for Statistical Programme for Social Sciences).

Conclusion:

The experimental analysis of the given samples showed that there was highly significant increase in levels of MUFA, LA, DHA levels post supplementation. The percentage distribution of SFA and AA significantly decreased post treatment. The TBAR analysis showed that there was a significant decrease in oxidative stress post treatment.

INDUSTRAIL APPLIACABILITY

Capsule C was well tolerated in this patient population. No adverse events were reported in clinical study. The occurrence of abnormal laboratory values was low and similar in both placebo and capsule C groups. No apparent trends were seen and most were considered to be clinically insignificant. No clinically significant changes in mean ECG parameters were observed over the duration of the study; in all cases where abnormalities occurred, findings were deemed harmless, clinically insignificant, or normal by pediatric cardiologists. In regard to vital signs, no significant changes were seen between treatment groups and no significant changes occurred over time. No discontinuation is reported for safety reason. This is one of the significant finding, since atomoxetine and other standard treatment modalities (methylphenidate) are responsible for more than 10% discontinuations for adverse events.
